I use Sandboxie when I'm surfing the web as my primary choice. It is easy to use, and easy to get downloads out of the sandbox after you are through testing them. Also, it is FREE. It has twice saved me from FBI ransomware. Don't waste your time with Toolwiz Timefreeze or Geswall.
Now I'm going to throw something new at you, when I am considering software from dubious sources, I use Sandboxie as well as Acronis Try and Decide which is part of their True Image software. Acronis Try and Decide, works very much like Shadow Defender.
For the rest of my anti-malware: Kaspersky Internet security 2015, Malwarebytes Pro, Hitman Pro, and Super- anti-spyware Pro. All of them are paid versions except Kaspersky Internet security 2015 which is on a 91 day trial. The free software i use is
VirusTotal Uploader, and AdwCleaner.
Also on my Chrome and Opera browsers I use HTTP Switchboard, which gives you total control of what is blocked and what gets through. It takes the place of about 4 to 6 other extensions. It blocks cookies, CSS, images, plug-ins, scripts, and XHR.
I have so Much Confidence in Sandboxie that on of my slower computers, where I can't Kaspersky, I use AVG Internet security. I have had no problems with running Sandboxi and AVG together.
In fact before I found this website, I was so disgusted with the paid Internet security suites, that I use Sandboxi with free avast, and free zone alarm firewall. With this combination I never had any problems either.
In fact I have so much confidence in Sandboxi that I might just use it with Windows defender and Windows firewall should this string of free antivirus trials ends.
By the way if you're using a backup cloud service, there are only two that use encryption. They are Spideroak and Tesorit. If you are using Google Drive, unless you encrypt things yourself everything that you store on Google Drive is open for any Google employee to see. I use Spideroak as my primary backup cloud service. In addition to the encryption, It checks for things to backup every five minutes, and you can synchronize with unlimited numbers of computers. Then I use Acronis True Image for weekly incremental image backup.
I think that if you use: 1) Sandboxie, 2) HTTP Switchboard, 3) an encrypted backup cloud service, and 4) you do weekly image backups to an external hard drive then you are as safe as you are going to get. Also, I truly believe that if you do the four things that I mentioned above, the type of antivirus or security suite becomes almost irrelevant.
